2. Sex, number of antennal segments

9Female, 12    9Male, 13   



3. Female, thorax, scutum, pitting in the central portion of the posterior half

2Pits dense and relatively uniform across the entire scutum, the average spacing being less than half a pit diameter, rarely if ever with any interspaces greater than the pit diameters, at least some pits touching one another in the center or the segment    4Pits dense to moderate in their spacing, the average spacing somewhere around one half to one pit diameter, with interspaces at time one pit diameter or greater    5Pits very distinctly sparser in the posterior half than in the anterior half of the scutum, the average spacing in the posterior half about two pit diameters or more    2Posterior half nearly entirely unpitted, standing in direct contrast to the closely pitted anterior rim   

4. Female, thorax, scutellum, pitting

3Scutellum almost entirely unpitted, with only a small number of pits in the middle of the segment, these pits with interspaces FAR greater than their own diameter    7Scutellum closely pitted, with many pits that are touching or nearly so   

5. Female, T1, presence or absence of iridescent bands at the apical rim

7Band entirely absent, with no traces even at the far sides    2Band present but interrupted, sometimes appearing only as small marks at the lateral sides    2Complete band present   

6. Male, head, mandible, dentation

5Simple, without a subapical tooth    4With a clear downward pointing subapical tooth located on the LOWER, outside margin of the mandible, well away from the tip of the mandible, in contrast to the usual placement of an extra tooth along the interior or upper edge of the mandible as found in other Halictidae   

7. Male, head, clypeus, pitting

3Pitting absent in at least the apical half, surface tessellated at most    7Pitting present in the apical half   

8. Male, hindleg, basitarsal integumental color

4Dark, brown to reddish-brown, about equal to the hindfemur in coloration, although sometimes there may be a SMALL amount of pale integument near the base    7Entirely light or very nearly so, yellow to off-white, clearly lighter than the hindfemur   

9. Male, T1, presence or absence of iridescent bands at the apical rim

8Band entirely absent, with no traces even at the far sides    2Band present but interrupted, sometimes appearing only as small marks at the lateral sides    2Complete band present
